What is the purpose of an indexTags setting of Group\:Work

[haggis999]

I pasted in the output from the mscript props command.

That pesky backslash in Group\:Work has always puzzled me. If I never need to enter any backslashes in the Properties dialogue boxes then all is clear.

I can't test it at the moment, but after I change that indexTags entry to Group:Work will the props output display an automatically-generated backslash or will that only appear in the actual config file?
